During a fire, no manual action is required to operate automatic fire dampers. They will automatically respond to temperature, smoke, or fire changes. When activated, the damper’s closing mechanism locks, sealing the duct opening and preventing flames and smoke from escaping. Inside a commercial property, ventilation ducts must not serve as a means of fire transmission, which is why these dampers must be part of the fire protection system. Equipped with reliable components and made of fire-resistant materials, these automatic fire dampers greatly enhance the safety of commercial, industrial, or even residential buildings.
